Application filed May 4, 1912. Serial No. 695,218.

To all whom it may concern:

1 Be it known that I, GILBERT \V. Gooonmon, a citizen of the United States of America, and residing at Bridgeport, in the countyot Fairfield and State of Connecticut, have 1neffective improved device for this purpose.

' present invention.

ing ring;

cated by the line 7-7, Fig. 2.

In the accompanying drawings, Figure 1 is a side elevation partially in vertical section, of a shade holder embodying my invention in one form and mounted on an electric lamp socket; Fig. 2 is a plan of the shade holder body; Fig. 3 is a plan of the support- Fig. lis a perspective of the latter; Fig. 5 is a side elevation showing one manner of assembling the parts on the socket; and Fig. 6 is a similar view of an alternative manner of assembly; Fig. 7 is an elevation of a portion of the shadeholder body indi- The. manner of supporting the globe or shade upon the holder forms no part of the In the example illustrated, I have shownvthe common self-centering spring wire 10, the supporting guide loop 11, and recurved ends 12 and 13 of which pass through slots in the peripheral skirt of the holder in well understood manner.

The holder is supported upon the customary bead 14 of the lamp shell 15 through an expansible ring 16. As here represented this ring comprises a cylindrical collar portion 17, fitting the shell 15 above or below the bead in adjusted position as will be hereafter explainedya second section 18 inclined outwardly therefrom and overlying the supporting bead 141; and a coned section 19 connected to the section 18 by the narrow in- Wardly ofi'set flange 20 and situated below or above the bead 14 depending upon the manner of adjustment, but in anyevent, opposite to theposition of the collar 17. This coned section 19 has spaced around the same a plurality of outwardly project-ing ribs 21 projecting over and'spaced slightly above the flange 20 to receive the flange 25 of the shade through the recesses holder body. Slots 22 are cut in the flange 20 to permit the metal to bend in slightly at" the lower ends of the ribs 21 during adjustment. Spaced between the ribs 21 are inwardly-projecting, bead-engaging shoulders 23 at the base of the coned section 19. For greater rigidity it is advisable to form one of these shoulders 23 adjacent each end' of the split ring as shown. I

The central aperture 24 of the shade holder body is bounded by a narrow flange 25, the diameter of which 1s greater than that of the head 14 so that the holder may be passed over the latter. A plurality of recesses 26 corresponding in number and location to the ribs 21 on the expanding ring are formed in the flange, while in the arcs between them are formed pairs of bumps 27. An annular stiilening rib 28 may be formed around the flange 25 to add to the'rigidity of the structure. To assemble the parts, the ring 16 may be adjusted with the collar 17 lying either below (Fig. 5) or above (Fig. 6), the bead 14 on the socket shell. If it is to be adjusted below as in Fig. 5, the shade holder body is first passed up over the head 14, as shown. When the ring is in position the shade holder is pressed down, the ribs 21 passing 26 in the flange 25', until the latter engages the flange 20. Rotation of the parts now with relation to each other passes the flange 25 beneath the lower edges of the ribs 21, thus preventing endwise separation of the parts, while continued rotation springs the lower end of each rib 21 over one of the bumps 27, thus frictionally locking the parts together against further relativerotation. While the adjustment of the holder upon the ring prevents the latter from expanding and thus confines it to the supporting bead. 14, the frictional engagement bet-ween the ring and the bead is less than the frictional engagement'between the holder and the supporting ring, so that the latter are rotated as a unit on the head after assembly.

Should the ring be adjusted as shown in Fig. 6, the holder is pressed upon the ring after the latter has been positioned. The engagement of the parts is the same, but the shade holder is now supported noton the flange 20, but upon the edges of the ribs '21,

andthe ring engages the head through the cooperating elements on the shade holder" adapted to be broughtinto engaging relation with the related elements on the expansible ring from above or below the bead depending upon the manner of adjustment of said ring.

2. A shade holder of the character described, having means for mounting the same upon a supporting bead, said means comprising an independent expansible ring adjustable upon said support-ing bead, a peripheral flange on said ring, a coned section rising from the flange and ribs thereon overlying said flange, in combination with a recessed flange on the shade holder body passed over said coned, section and turned in adjusted position to engage between said porting bead in adjusted position,

peripheral-flange and the overlying edge of said ribs.

3. A shade holder of the character described having means for mounting the same upon a supporting bead, said means comprising, as an' element thereof, an independent expansible ring engaged by the.

body portionv of the shade holder in assembled condition, said ring having a cylindrlca'l portion, a portion overlying the supand a ribbed port-ion connected thereto by a perforated inwardly oflset'flange, substantially as described.

4. A shade holder of the character described having means for mounting the same upon a supporting head, said means comprising an independent ring elementadapted to be positioned over the supporting bead, and a central flange-on the shadecarrying body of the holder, adapted to be freely passed over the supporting bead, said flange being recessed on its inner periphery and having engaging projections pressed up therefrom, to engage with cooperating elements on the independent ring element, substantiallyas described.

. 5. A shade holder ofthe character described having means for mounting the same upon a supporting bead, said means comprising an independent ring element adaptedto be positioned over thesupporting bead, and a central flange on the shadecarrying body of the holder, adapted to be freely passed over the supporting bead, said flange being recessed on its inner periphery and having engaging projections pressed up therefrom, to engage with cooperating elements of the independent ring element, together with an annular stiflening rib-surrounding said flange, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses.
